Tangentiality
Pronunciation: tan-JEN-shee-AL-ih-tee
A thought process disturbance in which a patient's replies to questions veer off onto loosely related topics and never return to the original point.
Full Definition
Tangentiality describes a pattern of speech in which the patient begins to answer a question but consistently drifts to related, oblique topics without returning to the original line of thought. It is less disorganized than loosening of associations but more disruptive than circumstantiality, which at least eventually reaches the point. In MSE documentation, tangentiality is recorded under thought process. Editors must not substitute 'tangential thinking' and 'tangentiality' as if they were freely interchangeable; 'tangential thinking' is the descriptive noun form and 'tangentiality' is the clinical shorthand used in structured documentation.
Usage
Usage note: Belongs under 'thought process' in MSE, not 'thought content.' Do not use as a synonym for circumstantiality; they describe distinct degrees of thought-process disruption.
